LRFD Information

All
structures - both state and local - that have the Type
Selection meeting held on or after October 1, 2006 must
be designed using the new LRFD specifications. Currently the primary
design specification for California structures
consists of the following:

The Seismic
Design Criteria will continue
to be the governing specification for the seismic design
of structures. Other Caltrans
manuals that govern structure
design such as Bridge Design Aids and Bridge
Memos to Designers will eventually
be updated in order of importance to design production.
The Bridge
Design Practice manual will
eventually be rewritten.
